welcome to HealthcareMagic ,
In your case , we need to take less calories and work out more to burn excess fat in the body.
There is no hard and fast rule about specific diet only.
Just remain away from high calorie food like sweets , carbohydrates like in bananas , potatoes , and fried food for about 2 weeks.
Exercise twice daily like aerobics
and jogging gradually building up your stamina.
You need to concentrate more on fitness development that will correspondingly reduce your weight.
